`To all whom it may concern.'

Be it known that I, HARVEY S. BERRY, a citizen of the United States,residing at Milford, in the county of Ellis and State of Texas, haveinvented a new and useful Cotton-Chopper Attachment, of which thefollowing is a specification.

This invention has relation to a cotton chopper attachment especiallyadapted to be applied to the frames of cultivators and it consists inthe novel construction and arrangement of its parts as hereinafter shownand described.

The object of the invention is to provide a simple and an effectivestructure adapted to be easily and quickly applied to the frame of acultivator and operatively connected with one of the wheels thereof andwhich may be used for the purpose of thinning or chopping outundesirable plants in a row of cotton.

With the above obj ect in view the attachment includes bearings adaptedto be applied to the arch bar of the cultivator and in which isjournaled a shaft. Means is provided for operatively connecting the saidshaft with one of the supporting wheels of the cultivator frame and thesaid shaft carries a beveled pinion. A cross bar is supported by saidbearings and carries a subshaft which in turn is provided with a beveledpinion which meshes with the first pinion. A frame is connected with thecultivator frame and means is provided for raising or lowering the firstsaid frame and means is provided for connecting` the first said framewith the beams of the cultivator whereby the frame will move laterallywith the said beams. rlhe rear end of a crank shaft is journaled in thelast said frame and the forward end of the said crank shaft is connectedwith the said sub-shaft by means of a universal joint. The arm of achopping hoe is mounted upon the crank of the said crank shaft and alink connects the upper end of the said arm with the frame of thecultivator.

Figure 1 is a side elevation of a cultivator showing the cotton chopperattachment applied thereto. Fig. 2 is a front elevation of the cottonchopper attachment applied to the frame of a cultivator. Fig. 3 is aplan view of a shaft and bearings which form parts of the invention.Fig. 4C is a detail view of a frame which is a part of the invention.l

The cultivator frame to which the attachment is applied includes theusual arch axle 1 mounted upon supporting wheels 2 and having an archbar 3 to which is connected the rear end of a tongue 4f in the usualmanner. Bearings 5 are attached to the end portions of the arch bar 3and a shaft 6 is journaled for rotation in the said bearings. A beveledgear wheel 7 is fixed to the intermediate portion of the shaft 6 and asprocket wheel 8 is fixed tothe end portion thereof. A sprocket rim 9 isattached to the side of one of the wheels 2 and a sprocket chain 10passes around the wheels 8 and 9 and is adapted to transmit rotarymovement from the wheel 2 to the sprocket wheel 8. The sprocket wheel Sis loosely journaled upon the shaft G and is provided with a clutch hub11. A clutch member 12 is slidably mounted upon the shaft G and isadapted to engage the hub 11 of the wheel 8. A lever 13 is suitablyfulcrumed upon the frame of the cultivator and at its working endengages the clutch member 12 and when swung is adapted to move the saidclutch member into engagement with the hub 11 or out of engagementtherewith. A cross bar 111 is mounted upon the bearings 5 and isprovided with a bearing 15. A sub-shaft 1G is journaled in the bearing15 and is provided at its forward end with a beveled gear wheel 17 whichmeshes with the gear wheel 7 upon the shaft 6.

Vertically disposed guides 18 are attached to the intermediate portionof the arch axle 1 and rods 19 are slidably mounted in the said guides18. A cross bar 2O is carried by the lower ends of the said rods 19. Across bar 21 is adjustably attached to the upper portions of the rods 19by means of clamp nut-s 22 which are screw threaded upon the said rodsand whichbear against the upper and lower sides of the said cross bar 21in the manner as indicated in Fig. 2 of the drawing. A lever 23 isfulcrumed upon the intermediate portion of the arch axle 1 and itsworking end is operatively connected with the cross bar 21. A segment 24is located adjacent to said lever and the Y shaft `28.

movement when passing over the plants.

I 'A' cross bar 35 is connected at its ends -36 and the lower portion ofthe frame 26 is lever ,carries a spring actuated pawl 25 which isadaptedto engage the teeth of theA said segment 211. An approximately V- shapedframe 26 is slidably mounted upon the cross bar 20 and the said frame 26is provided with rollers 27 which bear against the upper and loweredgesof the said cross bar 20 and serve as anti-friction devices. The rearend of a crank shaft 28 is j ournaled in the lower or choppingedgeportion of the V-shaped frame 26 and the forward endof the saidshaft 28 is operatively connected with the shaft 16 by means of auniversal joint 29. rl`he intermediate portion of a hoe arm 30 ispivoted upon the crank of the shaft 28 and the said arm 30 is providedat its lower end with a hoe blade 31. Bearings 32 are connected with anyappropriate part of the yframe of the cultivator and a shaft 33 isjournaled in the said bearings 32. Arms 34 are rigidly attached at oneend to the shaft 33 and at their other ends the said arms convergetoward each other and are pivotally connected with the upper end of thehoe Varm 30. The arms 34 extend transversely across the axis of thecrank shaft 28 and the arm 30 also lies transversely across the axis ofthe said shaft 28. Consequently the pivotal connections between the arms34 and 30 are at one side of the axis of the shaft 28 while the hoeblade 31 and the shaft 33 are atthe other side of the axis of the Whenthe parts are applied to the frame of a cultivator as indicated thelever 13 is moved so that the clutch member 12 is in engagement with theclutch hub 11 of the wheel 8./ As the frame is drawn along arow ofplants rotary movement is transmitted from the wheel 2 to the shaft 6and from the shaft 6 through the intermeshing gear wheels 7 and 17 tothe` shaft 28. As the crank of the said shaft 28 rotates above the axisof the shaft, the hoe arm 30 is reciprocated in a vertical plane and atthe same time is mo-ved longitudinally by reason of the fact that litsupper end is connected with the free ends of the arms 34; which in turn.are rigidly connected with the journaled shaftf33. Thus the hoe blade31 is caused toitravel in an orbit and is in a depressed position whenits chopping edge is moving towardthe row of plants-and is in anelevated position when its chopping edge is disposed in the directionopposite to its Thus it will be seen that as the device passes along therow of plants the hoe blade will chop out plants at intervals and leaveplants standing in the row between such intervals.

with the intermediate portions of the beams is slidably located. Thesaid rod 38 is mounted at its lower end upon the cross bar 35'.Consequently as the said' beams 36 are swung laterally, the frame 26will move laterally upon the cross bar 20 and thus the rear portion ofthe shaft 28 will be moved correspondingly and the chopping operationwill at all times occur approximately midway between the beams 36.

Thus'it will beseen that a simple attachment is provided which may beapplied to the frame of a cultivator for chopping out Yundesirableplants while the row is cultivated and that in its application to theframe of the cultivator it 1s not necessary to alter or mutilate thesaid frame or disturb the normal relations of the parts of theoultivator.
